To all whom it may concern:

Be it known that I, RAY E. KELLOGG, a. citizen of the United States, residing at Los Angeles, int-he county of Los Angeles and State of California, have invented new and useful Improvements in Horn Signaling Devices, of-which the following is a specification. 5

This invention relates to improvements in signaling'devices and particularly to horns for automobiles or other vehicles.

adjustment for producing a variety of tones and of blending aplurality of tones to pro- In the accompanying drawing forming a' part of this specification, Figure 1 is a side elevation of ahorn' signaling device oonstructed. in accordance with the firesent invention; Fig. 2 is. a transverse sectional r The details of the invention will now be more particularly described,-reference being had to the said drawing in which 1 indicates a drum-which is preferably of metal. and is provided" with a hub 2 and a connecting we portion 3. The web portion 3 is preferably located nearer one end of the hub than the other so as to form a larger compartment upon one side of said web than upon the other as shown in Fig. 2.

Fitting upon the ends of the drum are diaphragms 4 and 5'which are adapted to be held in'place upon the drum by means of' inwardly pro ecting flanges Sand 9 overhang the edges of the diaphragms 4 and 5 suflicientlytofirmly hold them in place upon the edges ofthe drum. The rings -6 and 7 are perforated at intervals and" are connected I by which they ma be drawn toward each other v and caused 'to firmly hold the said' diaphragms in place.

beveled inwardly as shown at 16 and 17 so as to form recesses opposite the apertures 14 and 15.

Adjustable rings 18 and 19 are also stem 13 is perforated at 14 and 1 5, a series hub 2. The said edges of the hub are usually I threaded upon the stem 13 and are adjusted quite close to the edges of the hub 2 so as to form openings for air to escape of a suitable size to pro rly act upon the adjacent inner edgesof e diaphragms in producing sounds or signals. Lock rings 20 and 21 are also secured upon the stem 13 so thatafter the rings 18 and 19 have been adjusted they may be locked in position.

The stem 13 is adapted to. be coupled with a tube or pipe 22 so that air may be forced into the said stem and outwardly through the apertures 14 and 15 to produce the sig:

nal sounds. The air escaping between the edges of the rings 18 and 19 and the hub .2

will impinge upon the edges of the dia-'- phragms 4 and 5 so as toproduce whistling, or other like sounds. j

- It will be understood that the sounds may be varied not only by the'adjustment of the rings 18 and19 with respect to the edges of the hub but also by the thiclmess of the diaphragms 4 and 5 as well as by the size of the central openings therein 11 and 12. The

character ofthe sound produced may also be further varied by the size of the openings or chambers formed upon each side of the web 3. The relative size of the chambers upon opposite sides of the said web will also produce a difierence in the blending of the sounds so that any pleasing-or other sound may be accomplished as found desirable. WhatI claimis:

, comprising a drum ertured heads, apartition within the dividing the space between the said heads into separate compartments, and

means for forcing a fluid aga'inst'the edges of said apertures. 2. A signal apertures,fthe drum bein provided wit separate chambers .of 'di 'erent depths ardevice comprisinga havingheads formed with sound producm 10s h nd s h f .said head's, and

means moulited upon saiddrum for delivering air or other fluids under pressure against the edges of said apertures.

3. A signaling device comprising a drum having a perforated hub structure adapted to direct air'under pressure, the said drum carrying sounding portions adapted to be fifi'bected by the an expelled from the said 4. A signal device, comprising a drum mounted on a hollow perforated hub having a partition dividing the drum into compart ments of difi'erent sizes, each compartment having sound outlet openings, and means for forcing a fluid through the perforations in said hub against the edges of said sound outlet openings.

5. A signal device comprislng a drum 1 having a web portion dividing the drum into different sized. compartments, a perforated hub portion within said drum,

' adapted to deliver air or other materials under pressure at the center of the drum, the heads having openings opposite the air outlets whereby sounds are produced.

6. A signaldevice comprising a drum having a hub portion, a stem inserted in said hub and having outlet passages formed 0pposite the edges of the hub for delivering air or otherniaterials from the said stem, adjustable members mounted upon said stem, and controlling the passage of air from the perforations, the drum heads having' central openings surrounding the air outlets, and rings for binding the said heads tothe said drum.

In witness that I claim the foregoing I have hereunto subscribed my. name this th day of July, 1911.
